Pressure Controlled Diaphragm Pumps Pressure controlled diaphragm pumps provide boat owners with a fresh water system that is as easy to use as their domestic water supply - with the versatility to offer full flow or a trickle. The pump is controlled by a switch which senses the pressure drop when a faucet is opened and activates the pump; it turns off when the system pressure builds to a pre-set limit as the faucet is closed. This system allows any type of faucet or shower valve to be fitted, from 3/8" (10mm) bore for minimum water use to 1/2" (13mm) bore for maximum flow. Choosing the pump for your needs is simple - just check your system size and the number of outlets you need to operate simultaneously and select the appropriate pump. Diaphragm pumps are self-priming, quiet in operation and can run dry for extended periods. It is always best to turn the pump off and then open a tap to de-pressurize the system when you are not using the boat as this will prolong pump life. Accumulator Tanks Accumulator tanks hold a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pump and pressure fluctuations, smoothing the flow and making the system quieter. Accumulators allow the pump to reach shut-off pressure more smoothly which reduces the on/off cycle which gives better control of hot water delivery. Our accumulator tanks all have a bladder that separates water from air. The bladder is pre-pressurised but may need fine tuning when installed to give the most efficient performance. One of the advantages of an accumulator tank is that they can dispense up to half of their capacity of water even when the pump is switched off. So the bigger the reservoir, the more water you have available without having to switch the pump on helping you wash your hands or clean your teeth without noise. Water Pressure Regulators Inlet water regulators are designed to protect your boat water system plumbing and fixtures from the possible high pressure of municipal water systems. Regulation is controlled at all flow rates by a pre-set spring and removable strainer traps debris. Both inline portable and permanent flush mount models are available in our new line of diaphragm sealed regulators. Aqua Filta™ Everyone knows how even drinking water straight from the mains at home can be less than perfect in taste, smell and colour. The activated carbon in Aqua Filta will absorb chlorine and other dissolved organics, whilst the silver impregnation ensures that bacteria do not multiply in the filter bed. In addition, the pre and post filters remove physical debris so that your water is not only safe to drink, but tastes good, smells good and looks good. Not available in USA Pumpgard™ Strainers Inlet Strainers are an essential part of any fresh water system using a diaphragm pump - protecting the valves from small particles in the water. Our Pumpgards™ have been designed for easy installation and rapid filter screen cleaning having a transparent bowl that screws off to allow simple, regular inspection. 3 Water Pressure Systems - Introduction www.jabsco.com 15 Water Pressure Systems - Introduction 3 16 www.jabsco.com Multi-Outlet Water Pressure Systems Water Pressure Regulators Pumpgard™ Accumulator Tanks PAR-Max 1, 1.9, 2.9, 3 or 4 Sensor Max VSD, Ultra Max, Dual Max VSD, 3 Chamber PAR-Max 1.9 3 YEAR WARRANTY PAR-Max 2.9 The NEW PAR-Max 1.9 and 2.9 Water System Pumps are designed for vessels requiring a smooth low flow, 12 or 24 Volt dc pump at an attractive low price.
